The SIM card kits are currently available free in the Republic online store, with free shipping via UPS Mail Innovations (note: if you need expedited shipping, you may instead wish to purchase a SIM card from Amazon for $5 and use their shipping).

This assumes that your phone is activated on the GSM network. If you purchased the phone elsewhere and then purchased a SIM card to activate it, it’s on the GSM network; if you purchased it from Republic, it could be on either the CDMA or GSM network (as noted above, only Republic staff can supply a CDMA SIM card).

Do you still have whatever might remain of the SIM card? If so, if you look at the lettering for the word “republic,” are all of the letters black/gray? Or, are some of the letters green? (If some are green, you have a GSM SIM card.)
